eshinreal SAS35X36 24-Port 12G SAS Expansion Card

SKU CH-PYAR-1VVHQ

Adds 24 SAS or SATA drives through six SFF-8643 ports using a SAS35X36 expander on a PCIe 3.0 x8 link

  • Product typeController Card
  • 24 drives at 12 Gb/s each through six SFF-8643 connectors
  • SAS35X36 expander chip scales capacity without RAID overhead
  • PCIe 3.0 x8 host link supplies full 12G bandwidth per lane
  • Dual-path design enables failover and multipath I/O setups
  • Low-profile bracket supports hot-swap bays and UEFI boot

24-Port SAS Expansion for High-Density Storage

The eshinreal SAS35X36 is a controller card designed to add massive drive connectivity to a server or workstation. It targets administrators who need to scale storage arrays beyond the limits of onboard ports. The card provides pure expansion without RAID functionality, making it suited for environments that handle redundancy at the software or HBA level.

PCIe 3.0 x8 Interface with Six SFF-8643 Connectors

A PCIe 3.0 x8 link supplies 8GT/s per lane to sustain full 12G SAS bandwidth across all lanes. Six SFF-8643 Mini-SAS HD ports each carry four channels, delivering 24 physical ports for SAS 12Gb/s or SATA 6Gb/s drives. The low-profile bracket fits restricted chassis slots, and dual-path support enables failover or multipath I/O configurations for enterprise resilience.

Expander Chip Architecture with UEFI Boot Support

The onboard SAS35X36 expander chip manages the 24-port fan-out while maintaining signal integrity for hot-swap operations. UEFI and BIOS boot support allows the host to initialise drives attached through the expander during POST. Power draw and thermals are governed by the host slot and chassis airflow, with no active cooling components mounted on the card itself.

Questions about this item

What bandwidth does the PCIe 3.0 x8 interface provide for the 12G SAS ports?

The PCIe 3.0 x8 host connection delivers 8GT/s per lane, which supplies the full 12G SAS bandwidth across the 24 ports.

What bracket and slot height does the card need for mounting?

A low-profile bracket is included, so the card fits in a low-profile or half-height PCIe slot.

How do I connect the card to the host and to the drives, and what is the common cabling mistake?

Use two SFF-8643 x4 cables from the host to the card's host ports, then six SFF-8643 x4 cables from the card's expander ports to the backplane; the frequent error is plugging drive cables into the host ports instead of the expander ports.
